LOADING DEVICE.

coal from the shaker screen of the coal mining machinery into cars forshipment. Herebefore this soft lump coal has been loaded from the shakerscreen into the car which causes a great deal of the coal to be brokenup and the purpose of this invention is to provide means whereby thecoal may be lowered into the car with the least breakage possible.

\Vith these and other objects in view, my invention consists of a novelconstruction, formation and arrangement of parts which may be readilyand manually operated by one person and which will be fully hereinafterdescribed, claimed and particularly pointed out in the drawings inwhich:

Figure 1 is a side elevation of the loading device embodying myinvention, showing the receiving pan in dumping position in dot-tedlines and in a horizontal position to permit a box car to pass; Fig. 2is a top plan of the same; Fig. 3 is a front elevation of the same, andFigs. 1 and are detail perspective views of the hangers.

Referring now more particularly to the drawings wherein like parts areindicated by like references throughout the several views, the numeral 1indicates generally the frame for supporting the loading mechanism whichconsists of a plurality of vertical supporting posts 2 which areanchored in the ground as at 3. The rear posts being connected byhorizontal beams 4 and the front posts 2 are connected by two transversebeams 5 suitably braced as at 6, the front and rear portions of theframe being connected by diagonally extending brace beams 7.

Secured to the supporting post 2 and the diagonal brace beam 7 on eachside of the frame are inclined beams 8 forming a suit able track for thecarriage of the receiving Specification of Letters Patent.

pan 9. This receiving pan 9 is made of rolled steel having one side 10of greater height than the opposite side 11 and it is supported on acarriage 13 preferably cast in one piece of metal having transverse ribslt and upwardly extending lugs 15 to which is riveted or otherwisesecured the pan 9. This carriage 13 is secured at one end to atransverse squared axle 16 by suitable brackets 17 which is clearlyshown in Fig. 1 of the drawings and which consist of a plate 18 adaptedto rest on the squared face of the axle having apertured lugs 19 throughwhich extends suitable bolts 20 connecting the same to clips 21 and avertically extending aperture portion 22 which is bolted or otherwisesecured to the carriage 13. The carriage 13 is further braced bydiagonally extending rods 23. One end of each being secured to thecarriage and the other end to the axle 16 by hangers 24: which areformed of two castings 25, one of which being shown in Fig. 5 of thedrawing which consists of an end portion 26 provided with an opening 27to receive the spindle or end portion of the axle and a portion 28provided with a recess 29 to receive the squared portion of the axlewhich will obviously prevent the hangers from turning when the twocasings are secured together by means of bolts extending through theapertures 30 mounted in the winged portions 31, each of which isprovided with a recess 32 one of which to receive the end of the brace23 and the other to receive the end of a brace not shown which can beconnected to the I beam 33 which will be hereinafter described when itis desired to brace the same.

Mounted on the ends of the axle 16 are flanged wheels which are adaptedto run on the tracks formed on the inclined beams 8 and are preventedfrom running off of the track by stops 35 which are suitably secured tothe lower ends of the said beams.

Each of the ribs 14 of the carriage 13 is provided with openings toreceive the I beam 33 which is secured thereto. The opposite end of thesaid I beam is adapted to slide between two rollers 36 mounted in atruck 37 which is adapted to slide on a track formed on two diagonallyextending beams 38.

Secured to and spaced from the center of the transverse beam 5 arevertically extending beams 39 having horizontal beams 40 extendingtherefrom between which are secured the beams 38. One end of each of thetransverse beams 5 extends beyond the vertical post 2 and said ends areconnected by a vertical member 41. And journaled in bearings formed onthe members 39 and 41 are shafts 42 and 43.

Spaced from one of the beams 4 by means of braces 44 is a beam 45 andjournaled in hearings on said beams 4 and 45 are shafts 46 and 47.

Each of the shafts 46 and 47 has a large and a. small sprocket wheel,the small sprocket wheels being connected to the shafts 42 and 43 bymeans of endless sprocket chains 48 while the larger sprocket wheelshave each mounted thereon endless operating chains 49 and 50.

A cable 51 is secured at one end to the carriage 13 and is adapted to bewound on the drum 52 mounted on the shaft 42 when drawing the receivingpan up the inclined track by the operator pulling on the chain 49 in thedirection of the arrow as shown in Fig. 1 of the drawing, and byreleasing the same the carriage will return to the lower end of thetrack. To prevent the carriage from tilting I connect the truck 37 inwhich slides the I beam 33 to a drum 53 by means of a leather belt 54whereby pulling the chain in the direction of the arrow as shown in Fig.1 the belt 54 will be released and the truck 37 will run up the inclinedtrack to the position as shown in dotted lines in Fig. 1 of the drawingby the weight of the receiving pan 9.

A cable 55 is connected to the carriage 13 and runs over guide pulleys56 and has sectional counter weights 57 mounted thereon. Another cable58 which is adapted to be wound on a drum 59 formed 011 the shaft 42 hasalso mounted on the end thereof sectional counter weights 60. Theseweights have a tendency to draw the carriage 13 up the inclined trackthereby permitting the same to be operated by one person.

The frame which supports the loading mechanism is to be placed beside asuitable shaker screen which is indicated by the numeral 61 whereby thecoal coming from the screen will be carried to the pan 9 and then bedropped in the car 62.

A diagonally extending angle iron 63 is riveted or otherwise secured tothe shaker screen which directs the coal to the center of the pan 9, andthe side 10 of the same will prevent the coal from running over thesides thereof.

The pan 9 is mounted to one side of the center of the car which willdirect the coal to the center of the car as shown in Fig. 2 of thedrawing.

Sheathing boards 64 are secured to the bottom of the carriage 13 toprevent the carriage from injury by contact with the coal in the car 62during the movement of said car.

It will be understood from inspection of the drawings and especiallyFig. 1, that the operation of the machine is capable of being controlledby the chains 49 and 50 by hand. The chain 49 when moved in thedirection indicated by the arrow will so actuate the shaft 42 throughthe medium of the chain 48 as to wind up the cable 51 on the drum 52 andpull the carriage 13 with the I-beam 33 upwardly on the inclined beams8, the beam 33 moving readily between the rollers 36 mounted in thetruck 37. When the carriage 13 has reached its uppermost position it maythen be turned to a horizontal position by moving the chain 50 in thesame direction as heretofore described in connection with the chain 49,thus sliding the truck 37 downwardly on the inclined beams 38 and thecarriage l3 and beam 33 will then be in the horizontal position asindicated by the broken lines in Fig. 1 and will not interfere with thepassage of cars under the frame of the machine.

In using the device for filling cars when the parts are in the positionshown in full lines in Fig. 1, the carriage 13 carrying the pan 9 may beraised and lowered as desired by operatin the chain 50, moving the chain50 in the direction indicated by the arrow in Fig. 1 will rotate theshaft 43 in the direction necessary to permit the weight of the carriage13 and the pan 9 to descend by gravity and correspondingly to lift thefree end of the beam 33 upwardly moving with it the truck 37, theextreme position of this movement of the carriage and beam beingindicated in broken lines in Fig. 1, and it will be apparent that byproper manipulation of the chain 50 the carriage and beam may be tiltedat any angle between the incline shown in broken lines and full lines soas to properly trim the car.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. In a loading device of the character described a frame, an inclinedtrack mounted on said frame, a receiving carriage adapted to travel onsaid inclined track, an I-beam connected to said carriage, a guideformed at one end of said frame, said I-beam adapted to slide in saidguide a cable connected with said carriage, and means for operating saidcable.
